TRANSCRIPT
COST Action 634On- and Off-site Environmental Impacts
of Runoff and Erosion
prepared by A.-V. Auzet, J. Boardman, K. Helming, M. Kirkby,J. Poesen, J. Rejman, P. Withers and others
build on expertise of COST 623 « Soil Erosion & Global Change » and COST 832 « Quantifying the Agricultural Contribution to
Eutrophication »
COST 623 & COST832: what did we learn ?
wide range of situations in the 20 participating countries similarities in group of regions (same trends in
climate/geomorphology and land use) high variability of patterns of surface characteristics due
to interactions between climate, land use, land management, socio-economic factors and policy
need for land use & climate change scenarios from representative areas / landscapes
agricultural contribution to eutrophication scale issues in processes (surface degradation,
roughness and connectivity…) and scale issues in socio-economic drivers…
need for appropriate and cost-effective control measures
knowledge on processes of runoff and erosion: application to soil protection ?
• The translation of scientific achievements into innovation and optimisation of soil protection and land management remains very limited
• Large gaps exist between knowledge and application at different scales from farm to small regions
• Main drivers include socio-economy and policies• soil protection strategies suitable for
implementation in practice requires mutual co-operation of scientific expertise, political interest, and practical experience
Main objectives
• coordinate and synthesise European soil erosion research in the contexts of land management and policy formulation that encourage soil protection and reduction of on- and off-site impacts of runoff and erosion
• identify and analyse the barriers at all levels, (scientific, political, administrative and management)
• develop tools and methods to support decision making in the sustainable management of erosion-sensitive areas at the farm level including the implementation of soil protection measures.
• develop an integrated understanding of on- and off-site impacts at the catchment scale
Planned Working Groups
• WG1: Policy issues in the implementation of sustainable land use
• WG2: Sustainable Farm-Scale Management
• WG3: Catchment integration of On- and Off-site effects
Policy issues in the implementationof sustainable land use
• co-ordinate European research efforts on policies that encourage soil conservation and reduction of off-site impacts of runoff and erosion (incl. impacts of phosphates and herbicides assoc. with soil)
• policies that lead to best practice• methods include the collation and analysis of existing
data, and the analysis and evaluation of successes and failures
Sustainable Farm-Scale Management
• research on tools and methods to support decision making in the sustainable management of erosion-sensitive areas at the farm level
• identify suitable indicators for assessing the sustainability of different management practices with special emphasis on runoff, soil erosion, loss of organic matter and phosphorus transport,
• catalogue of regionally adapted best management and soil conservation practices, develop adequate management techniques,
• tools to assess the effectiveness and efficiency of agricultural management and soil conservation practices, delivering data like gross margin and potential water erosion risk,
• integrated analysis of available data to check interrelated effects with other economic and environmental targets at farm level.
Catchment integrationof On- and Off-site effects
• Runoff generation and accumulation for catchment areas• Soil erosion, transport and deposition on hillsides and
downstream / off-site • Transport of non-point source nutrients and pollutants associated
with sediment• Transport of Soil Organic Matter and associated nutrients• Modelling, including particular attention to up-scaling and to the
representation of field to farm-scale heterogeneity at the catchment scale; adaptation of existing Models in a format usable by all range of potential users
• Monitoring, including collation and analysis of existing data • Field experiments to evaluate water, sediment and nutrient/
pollutant transfers
